如何在Ctrl中发送Ctrl + a然后d [英] How to send Ctrl + a then d in Expect

问题描述

因此，我试图将外壳程序生成到远程服务器，然后使屏幕运行一些命令，然后通过执行以下操作从所述屏幕分离:

So I am trying to spawn a shell to a remote server then make a screen run some commands and then detach from said screen by doing:

#!/usr/bin/expect

set server [lindex $argv 0]

spawn s "$server"
expect "#" { send "screen -S test\r" }
expect "#" { send \someescapeheretoreplicate ctrl + a then d to tell screen to detach }
interact

但是我不知道这些转义序列是什么，所以无法查找它们的表.

But I have no idea what those escape sequences are called so am unable to look up a table of them or what not.

推荐答案

如果我记得:

send "\x01"; send "d"

其中 \ x01 是Ctrl-A的值

Where \x01 is the value of Ctrl-A
